Question

एक सम पाँसे को उछाला गया है | घटनाओ `E_(1)={1,3,5},E_(2)={2,3},E_(3)={2,3,4,5}` के लिए निम्न के मान ज्ञात कीजिए -
(i) `P(E_(1)//E_(2))" व "P(E_(2)//E_(1))`
(ii) `P(E_(1)//E_(3))" व "P(E_(3)//E_(1))`
(iii) `P(E_(1)cupE_(2)//E_(3))" व "P(E_(1)capE_(2)//E_(3))`

Answer 1

Correct Answer - `(i) (1)/(2), (1)/(3) (ii) (3)/(4), (1)/(4)`
`n(E_(1))=3, n(E_(2))=2, n(E_(3))=4,`
`n(E_(1)capE_(2))=1, n(E_(2)capE_(2))=2, n(E_(1)capE_(3))=2`
सम संख्या के लिए `S={2,4,6}`
`rArr" "n(S)=3`
